1. A sensor system for measuring a glucose concentration in a host, the sensor system comprising:

  • a transcutaneous glucose sensor configured for insertion into a tissue of a host, wherein the transcutaneous glucose sensor comprises an in vivo portion and an ex vivo portion, wherein the transcutaneous glucose sensor is configured to generate a signal indicative of the glucose concentration in the host;

    a mounting unit configured to be placed on a skin of the host, wherein the mounting unit is configured to receive the ex vivo portion of the transcutaneous glucose sensor, wherein the mounting unit comprises sensor electronics, wherein the sensor electronics comprises a radio frequency module; and

    a receiver comprising;

    a processor configured to cause interrogation of the radio frequency module and to process data received during the interrogation; and

    a display configured to display an estimated glucose concentration value associated with the data received during the interrogation;

    wherein the radio frequency module is configured to transmit information representative of the glucose concentration to the receiver in response to the receiver interrogating the sensor electronics;

    wherein the processor in the receiver and/or a processor in the sensor electronics is configured to implement a sensor expiration period in response to the receiver interrogating the sensor electronics; and

    wherein the sensor system is configured to shut down the display of the estimated glucose concentration value upon the expiration of the sensor expiration period.
